A command for actively testing an authorized website or application for security vulnerabilities. It reads the target's allowed scope and existing reconnaissance before running checks for selected bug types.

Use it to hunt for issues such as SSRF, IDOR, cross-site scripting, SQL injection, OAuth flaws, race conditions, GraphQL problems, unsafe uploads, or business-logic bugs.

It focuses testing on permitted systems and the most relevant attack areas instead of probing blindly or testing excluded assets.

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.01660
Opus 5	$0.00000	$0.00830
Sonnet 5	$0.00000	$0.00332
Haiku 4.5	$0.00000	$0.00166

Security

Grade D, and why

hunt scanned grade D with 3 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Sends data to an external URLmediumData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

curl "https://target.com/api/webhook" -d "{\"url\": \"$INTERACT_URL\"}"

One request to 169.254.169.254 can return temporary IAM credentials.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 197 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/hunt

Active vulnerability hunting on a target.

What This Does

Reads program scope (in-scope assets, exclusions, payment behavior)
Loads recon output from recon/<target>/ if available
Detects tech stack and maps to primary bug classes
Runs targeted tests for the highest-ROI bug classes
Documents findings with exact HTTP requests

Usage

/hunt target.com
/hunt target.com --vuln-class idor
/hunt target.com --vuln-class ssrf
/hunt target.com --vuln-class graphql
/hunt target.com --source-code   (if repo is available)

Phase 1: Read Before Touching (15 min)

Read Program Scope

1. Go to program page (HackerOne/Bugcrowd/Intigriti)
2. Note ALL in-scope domains — only test these
3. Note ALL out-of-scope domains — never test these (Vienna: /advuew/* excluded!)
4. Note impact types accepted (some exclude "low" severity)
5. Check average bounty — signals program generosity

Read Disclosed Reports (Intel)

# HackerOne Hacktivity for this program:
# https://hackerone.com/TARGET_NAME/hacktivity

# Search by bug class:
# https://hackerone.com/hacktivity?querystring=TARGET_NAME+IDOR
# https://hackerone.com/hacktivity?querystring=TARGET_NAME+SSRF

# Extract from each report:
# 1. Which endpoint
# 2. Which bug class
# 3. What parameter
# 4. What check was missing
# 5. What they paid

Phase 2: Tech Stack Detection (2 min)

TARGET="target.com"

curl -sI https://$TARGET | grep -iE "server|x-powered-by|x-aspnet|x-runtime|x-generator"

# Stack → Primary bug class:
# Ruby on Rails  → mass assignment, IDOR
# Django         → IDOR (ModelViewSet), SSTI
# Flask          → SSTI (render_template_string), SSRF
# Laravel        → mass assignment, IDOR
# Express/Node   → prototype pollution, path traversal
# Spring Boot    → Actuator endpoints, SSTI
# Next.js        → SSRF via Server Actions, open redirect
# GraphQL        → introspection, IDOR via node(), auth bypass on mutations

Phase 3: Active Testing

IDOR Testing (highest ROI)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

hunt is a command published in the GitHub repository Mikacr1138/claude-bug-bounty (2 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,660 tokens. A static security scan graded it D with 3 findings (sends data to an external url, cloud metadata endpoint, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
